I'm using the default screenshot application that comes with Ubuntu gnome-screenshot
When I was using it earlier to take screenshots of the lock screen I had set a long time delay, but forgot to change it back after I'd finished. When I next took a timed screenshot I had to wait a long time for it to take because the delay was still set so long.
Clicking the icon to relaunch the screenshot application has no effect whilst the timer is in effect, I imagine there is probably a simple terminal command to shut down an application, but I don't know it! Is there a way to do this?
The one-liner you're looking for is:
Step1. Looking for the process numbers of gnome-screenshot by
ps ax
command in the terminal.Step2. Execute
kill <process_number>
.Step3. Insert the following command from the terminal:
Then, you can set Grab after a delay 0 second.
